Fantastically funny Wilf was shortlisted for the Laugh Out Loud Book Awards!

Meet Wilf. He worries about everything. He is a Mighty Worrier. And now the most evil man in the world is determined to takeover from the very beginning of time...

Things Wilf was worried about before:

1. Sleepovers.
2. Skeletons.
3. Being squashed flat.
